EYELETiNG-M ACHINE.

SPECIFICATION forming part of Letters Patent No. 605,574, dated lune 1 4, 1898. Application filed Junel, 1897. Serial-No. 638,880. (No model.)

.To all whom it may concern; Y Y I Be it known that I, SEYMOUR FIELD, 0 Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Eyeleting-Machines, of which the following is a specification. V

This invention relates to eyeletingmachines in which the operationsof advancing the chute to present an eyelet to the bottom set and of raising the bottom set to carry the lowest eyelet upwardly to the top set andat the same time withdrawing the chute are performed by a mechanism actuated by a treadle, said machines being typified in that illustratedin my former patent, No. 545,468, dated September 3, 1895.

One object of this present invention is to provide animproved mechanism for guiding the chute forwardly until it holds the last eyelet therein directly over the finger of the bottom set and then allowing it to drop vertically to deposit the eyelet thereon; and a11- other object of the inve'ntionis to lock the chute immediately upon its dropping to prevent any rebound or backlash of the same and to thereby insure the machine operating with the highest degree of efficiency and without any jarring or vibrating of its parts.

To these ends the invention consists in those improvements 'which'I have illustrated upon the drawings andfwhich I shall now proceed to describe in detail, and point' out in the claims hereto appende I Reference is to be had to the annexed drawings, and to'the letters'marked thereon, forming a part of this specification, the sameletters designating'the same parts or features,

, as the case may be, wherever theyoccur.

1 Of the drawings, Figure lrepresents 'a view in side elevation of an eyeleting-machine equipped with myimprovements. Fig. 2 is an enlarged View showing] the chute in its depressed position with its coacting parts looking it against a'rebound' Fig. 3 is a similar View showing the chute in' its retracted position. v

In the drawings, (t represents the fixed frame of the machine, having an overhang-- ing arm a, to which is affixed the top set I), the latter having a downwardly-projecting yielding finger b, which engages the work by entering the hole provided therein, as usual.

vided with theyieldingly-supported eyeletengaging finger c. The bottom set is vertically reciprocated by mechanism of any desired sort-such, for instance, as that illustrated and described in my former patent, No. 545,458. It engages the lowest eyelet in the chute and raising it to the top set inserts it in the work held upon the top set and cooperates with the latter in upsetting and securing it, all ina manner common to eyeleting-machines and requiring no detailed description. I

f. 01 represents the eyelet chute, which is formed in a well-known manner to guide the eyelets from a reservoir d at the upper end 0f,;the chute and present the lowest eyelet to the fingers c, said chute being affixed to a carrier d ,.which is pivoted at d to an operating-lever c, said lever being pivoted at e to the frame of the machine.

f represents the operating-lever, which "is pivoted at f to a downwardly-projecting arm or extension 0, on the supporting-frame, one

of the arms of the lever f being connected with a treadle, (not shown,) while the other arm of said lever is connected by means (not shown) with the bottom set and with a rockshaft a, mounted in the said arm a The rock-shaft is connected by an arm a) and a link j with the chute-supporting lever e.

NVhen the lever fis elevated or raised, the bottom set is depressed, and when itis lowered the bottom set is raised.

The chutecarrier d which, as already stated, is pivoted to the lever e,-is pivoted at its end, as at 70, to a bar orlink k, which guides it forward horizontally until the low Zest eyelet in the chute is over the bottom set and then drops itvvertically to leave the eyelet upon the finger c. The lowenend of the link is pivoted by a crank-pin or screw 0 to a diskl, journaled in theplate a of the frame, which disk has a tooth or stop Z, with which a spring-held pawl m is adapted to engage to lock the disk against movement, .The pawl is pivoted to the plate a by a pivot or screw m, and has an arm m which isarranged in the path of a roll d on the lower endof the chute-carrier, so as to be moved by it when the latter has reached the limit of its movement.

The crank-pin is so placed with relation to 0 represents the bottom set, which is pro- 5 gaged by the pawl the axis of the pin is substantially in the horizontal plane of the axis of the disk and the end of the chute is raised a quarter-turn of the disk, as shown in Fig. 3. Then when the chute-carrier is moved forward by depressing the lever fit is guided horizontally by the link swinging on the crank-pin 75* until the roll on the end of the chute-carrier engages the arm m and lifts the pawl m from engagement with the stop Z, at which the disk partly rotates, by reason of the weight of the chute, and the chute drops vertically under the tension of the spring 0, connected at one end with the carrier and at the other end with the lever 6, these movements accomplishing the placing of an eyelet on the yielding finger of the lower set.

In order to oscillate the disk Z partially from the position illustrated in Fig. 2 to that in Fig. 3, I employa pin n, projecting from the plate a and having a roller 'n, held thereon by a spring cotter-pin. It is so placed in rear of the link that when the upper end of the latter is drawn back by the end of the chutecarrier, acting under pressure of the lever c, the link swings around the roller 71 and pin n as a fulcrum, and its lower end rotates the disk far enough for the pawl m to drop behind the stop or teeth Z. To prevent the disk from rotating too far, the link is formed with an arm k and a socket 7;, which fit the roller and hold it from further movement. In addition to the socket 7c, the link has another socket k to fit the roller when it is depressed.

Besides guiding the chute-carrier and the chute during their horizontal and vertical movements the parts just described lock the chute against a rebound or backlash when it drops after depositing the eyelet on the finger of the bottom set-that is to say, when the roller 011 the end of the chute-carrier engages the arm m of the dog upon its moving forward, so as to disengage the latter from the disk, the link drops and the disk partly rotates until stopped by reason of the crankpin reaching a dead-center with the axis of the disk and the pivot 7t, at which point it is held by the link impinging against the roller a. lhus it will be seen when the parts are in these positions it is impossible for the chute to rebound or have any backlash, since it is looked as soon as they drop.

The improved devices which I have just described not only operate with a high degree of efficiency and accuracy to guide the carrier and the chute forwardly and vertically to place an eyelet upon the finger of the bottom set and then lock them against a rebound, but also operate noiselessly and without jarring or hammering.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is- 1. In an eyeletinganachine, the combina tion with the eyelet-setting devices, the eyelet-chute, and mechanism for operating said parts, of means for guiding the chute horizontally and vertically and for preventing a rebound of the chute at the end of its forward movement.

2. In an eyeleting-machine, the combination with the eyelet-setting device, the eyelet-chute, and mechanism for operating saidparts, of a guide for said chute to cause it to move horizontally forward and then vertically downward, and a lock for locking said chute at the end of its downward movement.

3. In an eyeleting-machine, the combination with the eyelet-setting device, the eyelet-chute, and mechanism for operating said parts, of a link for guiding said chute in its movements toward and from the eyelet-setting devices, and a lock forlocking said chute at the forward end of its movement.

4. In an eyeleting-machine, the combination with the eyeletsetting device, the pivoted eyelet-chute, and mechanism for operating said parts, of a link connected to the chute and to an oscillating pivot for supporting and guiding the chute in its movements toward and from the eyelet-setting devices.

5. In an eyeleting-maehine, the combination with the eyelet-scttin g devices, the eyelet-chute and mechanism for operating said parts, of a disk having a crank-pin and a link pivoted to the chute and to the crankpin, said link supporting the lower end of the chute and guiding it in its movements toward and from the eyelet-setting devices.

6. I11 an eyeleting-machine, the combination with the eyelet-setting devices, the eyelet-chute and mechanism for operating said parts, of a disk having a stop and a crankpin, a link pivoted to the chute and to the crank-pin, and a pawl for engaging the stop, and arranged to be operated by the chute for releasing it from engagement with the stop.

'7. In an eyeleting-machine, the combination with the eyelet-setting devices, the eyelet-chute and mechanism for operating said parts, ofa rotatable disk having a crank-pin, and a link connected to a pivot on the chute and to the crank-pin, and means for holding the parts with the axes of the disk, the crankpin, and the pivot on a dead-center to lock the chute.

S. In an eyeleting-machine, the combination with the eyelet-setting devices, the eyelet-chute and mechanism for operating said parts, of a disk Z having a stop Z and acrankpin 73, of a link is pivoted to the chute and t0 the crank-pin and havinga stop a pawl 171 having an arm m and a stop or pin it all cooperating for the purposes set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 26th day of September, A. D. 1896.
